The I/F Options control the voltages on the TX and RX connectors.

Please confirm that the attached equipment is capable of operating

with DC voltage applied to its RX and/or TX port prior to applying the

I/F Options settings. This could cause damage to equipment that is

attached to the receive and/or transmit port.

Satellite Setup

After changing a satellite configuration item, please wait for at least 15 seconds before

turning off the Modem power. This allows the Modem software time to write the updated

configuration to its persistent storage.

This list of satellites is the entry point to updating satellite data. The selected satellite

("Yes" in the selected column) is the one you have chosen on the Network page. (See

Figure 6-4) There are four (4) satellites allowed. "ZeroTest" is a keyword name that tells

the Modem to operate with a zero round trip delay for lab testing.

Clicking on a satellite Beam or BW Segment button brings up the corresponding Editor

screen. Clicking on an entry makes it active and it will then appear in the Satellite

Entry/Update fields. Data for the "selected satellite" may not be changed when the

terminal is active in a network.

Refer to Table 6-3 Satellite Database for data descriptions for this window.

Displays the computed range of I/F frequencies that the Modem will

use based on the selected satellite bandwidth segment and the block

up and down converters.

Allows selection of the internal frequency reference, or use of an

external 5 or 10 MHz reference to lock the internal reference.

This allows you to selectively enable 10MHz and/or +18V output on

the RX port, and 10 MHz and/or Ext Volts DC (VDC) output on the TX

port.
